  1. GREAT LAKES CARBON LLC INDUSTRIAL PRODUCTS LEADING SUPPLIER THE WORLD’S OF CALCINED PETROLEUM COKE (CPC)

  2. Oxbow Calcining, LLC • Nick Lyons – Project Engineer at Oxbow Midwest Calcining • Chemical Engineer • University of Illinois at Urbana-Champaign • Oxbow Corporation - 400 Employees Worldwide • 5 Calcining Plant Locations • 15 Rotary Kilns • 2.5 Million Metric Ton (MT) Capacity • Products Sold or Used in 28 Countries • Annual Purchase 3+ Million MT Green Coke • Greater than 35 Refinery Sources • Green Coke from 10 Different Countries

  3. How Much is 2.5 Million Metric Tons? • 1 Metric Ton = 2,204 lbs. • 2,500,000 Metric Tons = 5,511,557,000 lbs. • Density of Coke = 125 lbs/ft3 • 5,511,557,000 lbs. ÷ 125 lbs/ft3 = 44,092,456 ft3 In one year, Oxbow can process enough coke to cover a whole football field with a 980’ high pile!

  6. Quiz # 1 – Your Daily Routine • In your new Oxbow notebooks, make a list of everyday things that you use. • What bathroom products did you use? • What’s in your lunch? • What do you keep in your backpack? Locker? • Nick, why are you making me do this??

  7. What is Petroleum Coke? A By-Product! • By-Product from the Refining of Crude Oil (Solid Carbon) • Produced in a Refinery Coker Unit • Thermal Cracking Process • Uses Heat to Break Apart • Converts Low Value Long-Chain Hydrocarbons to Valuable Products (Gasoline, Diesel, etc.) • Petroleum Coke is a By-Product of the Coking Process • Coke is the Lowest Value Product Produced in a Refinery

  8. Types of Petroleum Coke Needle Coke Sponge Coke Shot Coke

  9. Refinery Coking Process Reaction inside of the Coke Drum takes place at 900oF & 80 PSIA!

  10. How Is Petroleum Coke Made? Long Chain Hydrocarbon + Heat & Pressure Petroleum Coke (Low Value By-Product) (Valuable Products)

  11. Oil Refineries Raw Petroleum Coke (RPC) Calcining Calcined Petroleum Coke (CPC) Created Process Over 65 Years Ago Process Flow

  12. Petroleum Coke Calcining Roasting Petroleum Coke at High Temperatures (2,500 oF) Removes Moisture and Remaining Hydrocarbons Increases Density, Physical Strength and Electrical Conductivity Product is Hard, Dense Carbon – Calcined Petroleum Coke

  13. Rotary Kiln Heating Zones Raw Coke Feed 25 - 400 C 500 - 1000 C Kiln Exhaust 1200 -1400 C Moisture Release "Heat Up Zone" Devolatilization Some "Calcining Zone" Desulfurization & Densification Burning of C & Gas Natural Gas "Calcined Coke Zone" 55 m (180') Air Key Control Parameters - Consistent Feed - Feed Sizing - Air Velocity / Draft Calcined Coke - Temperature Profiles

  14. Calcining Process RAW “GREEN” COKE HOT STACK RAW COKE PYROSCRUBBER KILN KILN EXHAUST GAS LINE COKE WATER SPRAY WATER LINE AIR COOLER EXHAUST COOLER CALCINED COKE to Storage/Screening/Shipment Mode

  15. Lemont Plant – Process/Material Flow

  16. Green Coke vs. Calcined Coke Green Petroleum Coke Composition Calcined Petroleum Coke Composition

  17. Critical Calcined Coke Properties HeliumReal Density (RD) ~2.070 g/cc Fills all pores with He Density of Coke Particles Only Density Sulfur Particle Sizing Coefficient of Thermal Expansion Ash (V, Ni, Fe, Si, Na, K, etc.) CO2 Reactivity Air Reactivity Hg Apparent Density (AD) ~1.07 g/cc Fills outer pores & void spaces between particles with Hg Density of Coke Particles & Inner Pores Vibrated Bulk Density (VBD) ~0.86 g/cc Density of Coke Particles with Inner Pores & Void Spaces

  18. Products that Require Petroleum Coke Graphite Pigments Aluminum Steel Chemicals Batteries

  19. Worldwide Petroleum Coke Picture Raw Coke Production 91 Million MTons Fuel Coke (Power & Cement) 68 Million MTons Graphite/Steel 1 Million MTons Calcinable Coke 23 Million MTons Calcined Coke Production 18 Million MTons Aluminum 14 Million MTons Other Pigment, Steel, Etc. 3 Million MTons

  20. Flexible Shipping Options Ocean-going Vessels Barges Railcars Trucks

  21. Synergistic Relationship with CITGO Green Petroleum Coke Water (Boiler / Utility / Potable / Fire) Air (Instrument / Utility) Fuel Gas Steam Transportation & Barge Loading Services Waste Water

  22. Energy, Efficiency, Sustainability • Our plant produces 1.4 Trillion BTUs/year from calcining pet coke. • By capturing 1,800-2,000 oF waste heat, the steam and power produced have no associated emissions. • 825,000,000 lb/yr steam to CITGO (450 psig & 460 oF) • 315,000,000 lb/yr steam to CITGO (600 psig & 680 oF) • 0.5 MW power used internally • This offsets approximately 70 tons/yr NOx and 100,000 tons/yr CO2 emissions that would otherwise be emitted to the atmosphere in supplying this energy. • Once a waste stream for refinery, pet coke serves as a major component in other industries worldwide.
